鲜茧交易中测定茧层率抽样方法的优化
OPTIMIZATION OF SAMPLING METHOD ON DETERMINATION OF THE COCOON SHELL PERCENTAGE IN FRESH COCOON TRANSACTION
【摘要】 研究表明采用定粒不定量或减少抽样数量等多种新的抽样方法,都能达到既准确反映交易鲜茧总体茧层率概貌,又省时省力、减少上茧浪费的目的,并且几种备选方法间也不存在显著性差异。但考虑到现实操作的可行性,以抽取500 g茧粒数的6.0%粒,重量随机的方法为宜。
【Abstract】 The study has shown that a number of new sampling methods such as the method of fixed cocoon number and non-quantitative,or reducing the number of sampling can not only accurately reflect the overall profile of cocoon shell percentage in fresh cocoon transaction,but also save time and manpower and reduce the waste of the reelable cocoon,and there is also no significant difference between the alternative methods.However,taking into account the feasibility of the actual operation,the weight random method that extracting 6.0% cocoon number from 500 g cocoons is appropriate.
